lVhile I have herein shown and particularly described the preferred embodiment of my invention, I do not Wish to be limited to such embodiment.

Having thus described my invention, I claim as new and desire to secure by Letters Patent a l. Braking mechanism including a brake shoe having a wheel flange-receiving recess, said brake shoe being provided with a duct leading to the flange-receiving recess and serving to transfer material to the wheel flange-receiving recess, which material is adapted to lessen the wear between the wheel flange and an engaging track rail, the material by being conveyed to the flange-receiving recess of the brake shoe, being applied to the wheel flange when the braking mechanism is operatedto apply the brake shoe to the wheel and its flange, I

2. Braking mechanism including a brake shoe having a wheel flange-receiving recess, said brake shoe being provided with means formed in the structure of the shoe for tra nsferring material to the wheel flange-receiving recess, which material is adapted to lessen the wear between the wheel flange and an engaging track rail, the material by being conveyed to the flange-receiving recess of the brake-shoe, being applied to the wheel flange. when the braking mechanism is operated to apply t io bra-lie shoe to the wheel and its flange 3. Braking mechanism including a brake shoe having a wheel flangereceiving recess, said brake shoe being provided with means for transferring material to the wheel flangereceiving recess, which material is adapted to lessen the wear between the wheel flange and an engaging track rail, the material by being conveyed to the flange-receiving recess of the brake shoe, being applied toithe wheel flange when the braking mechanism is 0peratedto apply the brake shoe to the wheel and its flange.

4. Braking mechanism including brake hearse shoe adapted to work upon a flanged railway wheel, said brake shoe being provided with means formed in the structure of the shoe for transferring material to the wheel flange, which material is adapted to lessen the wear between the wheel flange and a track rail, the means for conveying such ma terial to the wheel flange being normally out i of operative relation with the wheel flange but being brought into operative relation with the wheel flange by the braking mech anism when operated to permit of the transfer of such material thereto when the brake shoe is applied to the wheel.

5. Braking mechanism including a brake shoe adapted to work upon a flanged railway wheel, said brake shoe being provided with means for transferring material to the wheel flange, which material is adapted to lessen the wear between the wheel flange and a track rail, the means for conveying such material to the wheel flange being normally out of operative relation with the wheel flange but being brought into operative relation with the wheel flange by the braking mechanism when operated to permit of the transfor of such material thereto when the brake shoe is applied to the wheel. 7

Braking mechanism adapted to work upon a flanged railway wheel, andprovided with means-for transferring material to the wheel flange, which material is adapted to lessen the wear between the wheel flange and v In witness whereof, I hereunto subscribe my name this 3rd day of'February A. D., 1909. I
